Question , Choppy Playback

Jameswilsonmd1 · March 23, 2011, 6:55am

I am having trouble converting blu-rays to mkv fromat when the blu-ray is V-1 Video format , everytime i do it and put it on the wdtv hub it playbacks really choppy , i ran media info and here is what i got , ( i have a mac by the way ) , if someone could help me with my problem , maybe suject a few extra steps i could do to fix this that would be great,

also i used makemkv as my software, ive also tried pavtube and made it a mp4 but same problem occurs , i think the problem is in the v-1 codec used because i did a diffrent bluray that has a diffrent codex and it played back just fine

Not entirely sure, but I believe it could be a) something to do with the auto framerate on the HUB, which has caused choppy playback for some people or b) 25 Mbps is a lot !! Perhaps your file is simply too much to handle for the HUB.
